The EXPO 2015 has issued a medal available in various editions in the official souvenir shop, like for example with an outer ring of copper-zink and the inner core made of wood.

According to media reports this medal became right in the first days the most popular souvenir item of the retail centre. In the retail centre in the city some customers would buy more than one item only, one man even purchased 50 pieces at once! No wonder that the medal was temporarily out of stock.

All those, though, who cannot go to Milan but nevertheless wish to have an EXPO medal, may order one on the internet. At least for the time being the item is still available.
